A merry-go-round rotates from rest with an angular acceleration of 1.65 rad/s2. How long does it take to rotate through (a) the first 2.53 rev and (b) the next 2.53 rev?

2. Relevant equations

3. The attempt at a solution

I tried to do this and I converted the rev to radians by multiplying the revolutions by 2pi and then for (a) I divided 15.896/1.65 and got 6.28 seconds (15.896 is 2.53(2pi))and for (b) I divided 31.79/1.65 to get 19.3 seconds. What am I doing wrong here?
